Glass wools insulation products are made of fine, long inorganic glass fibers bonded by high temperature resin and is widely recognized for its energy conserving and sound insulating properties. Fibre glass insulation is used with great success in the process, building and air conditioning industries.
Glass wool is a thermal insulation that consists of intertwined and flexible glass fibers, which causes it to "package" air, resulting in a low density that can be varied through compression and binder content. It can be a loose fill material, blown into attics, or, together with an active binder sprayed on the underside of structures, sheets and panels that can be used to insulate flat surfaces such as cavity wall insulation, ceiling tiles, curtain walls as well as ducting. It is also used to insulate piping and for soundproofing.
